Yeah, I bought a 91 civic hatch. And with the lovely DPFI, I decided to put an old ECU in the car, just for ***** and giggles. The ECU, of course, flashes a code. Code 16: Fuel Injectors. Which is understandable because the ECU is MPFI, and the car DPFI. But what I'm wanting to know is if there is anyway of throwing in some bigger injectors, and that would smooth out the roughly 3oo RPM idle, or if it's a lost cause becasue the ECUs bugged for4 injectors, instead of 2. Let me know, something to do. Thanks.

 

u usin a si ecu if you are i would up the injetor size and get a gettodyne tuned chip in there and maybe u can get as much fuel as four injectors just a thought

 

That won't work...DX ecu is completely different than the Si ECU, gotta swap the injection systems (MPFI swap) and then you can use the Si ECU with it...

 

ya man. pop on a a6 head, or even better a y8 head w/ Si intake and dizzy and your set!
